Summary

The authors report that fluorine insertion into strontium(2)-copper-oxide(3) at ambient pressure causes related structural rearrangements to give superconducting strontium(2)-copper-oxide(2)-fluorine(2+) with a maximum transition temperature of 46 K. The structural changes previously initiated by the thermodynamic effects of high pressure are induced chemically under ambient conditions. The result is a superconducting oxy-fluoride in which fluorine plays a dominant structural role, rather than merely being an electronic dopant as in lanthanum(2)-copper-oxide(4)-fluorine(x) and neodymium(2)-copper-oxide(4-x)-fluorine(y).
